Frequency of Condenser Cleaning and Heater Exchange Cleaning
For every power plant unit there is a different optimum schedule for condenser cleaning. Economic comparative analysis can provide the maximum monetary return because of the gains in plant efficiency after cleaning; with additional consideration given to extended tube life. Each unit should develop its own cost-effective schedule for condenser cleaning

Main condensers should, at a minimum, be cleaned twice a year. Even if the cleaning does not substantially improve performance, this preventive maintenance for the extended tube life will easily justify the cleaning costs.

Condensers should be cleaned immediately after a shutdown. After cleaning, stagnant water should be removed from the condenser tubes to avoid corrosion.

If the time frame between cleanings is too long, the soft deposits easily removed may take on different characteristics and may become a harder material that is more difficult to remove.
